摘要
对纳米TiO_2掺杂金属盐后的光催化甲醛降解性能进行了研究。研究结果表明:适当钒掺杂改性提高了纳米TiO_2降解甲醛的能力,经过钒掺杂改性纳米TiO_2后其可见光范围的吸收明显增强;0.5%Fe+0.3%V复合掺杂改性具有较好的光催化效果,比单一金属元素掺杂效果好,其甲醛降解率可达85%以上。
The formaldehyde degradability by nanometer TiO2 that is metal - doped compound was studied. The result shows that the formaldehyde degradability and the visible light absorbency are improved by the V - doped nanometer TiO2. The nanometer TiO2 of 0.5 % Fe ＋ 0.3 % V doped has better photocatalytic activity than single V - doped nanometer TiO2. And it can degrade 85 percent formaldehyde after 24 hours.
